OOLUKN AND METHOD OF MAKING SAME.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I ALBERT G. Hmoms, a citizen of the United states residing at Kansas City, in the county of ackson and State of Missouri, have invented certain new and useful improvements in Columns and Method of Making Same, of which the following is a specification.

This invention relates to reinforced plaster or cement columns and to the method and recess of making the same, and my 0l)]2(2l. 15 to produce a strong and durable column ex edltiously and economically.

has this object in view the invention consists in certain novel and peculiar features of construction and in the novel method or process of making the columns, and in order that the invention me be fully understood, reference is to be ha to the accompanying drawing, in which- 0 1 e 1, is a pore active v ew of a part of a fi d xihle web bearing a coating of plaster or equivalent material and a flexible remforcement, the latter rest up on or being embedded in such mat 1g. 2, is a. plan view of the same with the reinforcements extending lon 'tudinally and transversely of the web. a 3, is a lan vlcw showin the coated rein orced we in process of eing rolled or wound upon a core mounted in a lathe. Fi 4 is an enla cross section taken on ta line IV -I of Fig. 3. Fig. 5, is an enlar ed longitudinal section of a part of the co umn, and showing also the core therein. Fig. 6, is a plan view showing the method or recess of making a column by winding t e web spirally thereon. Fig. 7, is an end view of a comgleted column before the core has been withrawn therefrom.

In the said drawing. 1 indicates a sheet or web of suitable proportion and of any suitable material, such, for instance, as paper. as shown, or wire gauze, and 2 indicates a coating of plaster or ccment upon such web. If it is desired to reinforce the plaster or ccmcntrcoated web, and this is particularly desirable where a paper web is employcdm so or flexible metal reinforcement 3 is placed upon the plaster or ccmcnt coating, which rclnforccmcm: may be woven wire or may consist of pieces of soft wirc arranged (liu onally, as shown in Fig. l, or longitudinal y or transverse] as shown in'Fig. 2, the dingonnl wiros being numbered 4- am] 5 respectively, and other wires 6 and 7 respectively. This plaster or cement coating is then rolled or wound upon a core 8 of any suitable construction or material.

For very small columns, such as porch and stairway balusters, the coated web whether reinforced or not, ma be wound by hand upon the core, the we forming a vehicle for the luster or cement and a reinforcement for e same when the column is completed and the moisture has evaporated therefrom. For larger column I prefer to mount the core in a lathe as in dicated at 9, and than by revolvi the core, wind the coated web upon it. y either method the column produced is of the type shown in Figs. 4, 5 and 7, and after the column has almost attained the proper diameter, it is given an external cost 10 of laster or ccment so as to bring it to cylin rical form as shown by Fig. 7, or it ma be applied to give the column a swelled c act or a tapering form, though it is obvious that these eifects may be obtained by the use of properly shaped cores.

The preferred method of applying the coatin 10 is to revolve the core and column in the athc and apply the material by means of a trowel or equivalent tool, it being noticed in this connection and by reference particularly to Fi 4, 5 and 7, that the inner end of the we is left uncoated a suitable length to completely incasc tho core in order to prevent the coating coming in contact with the latter and thus making it. difiicult or impossible to remove the core without injuring the column built upon it.

In F i 6 I illustrate the preferred method 0 malrin or building osts or other columns intende to support a \envy weight, that is to say, spirally wound columns. In this (OllSll'INfilOl'l the coated web will be spirally wound on the core in one direction, the web by preference, being a relatively nurrow coated and reinforced web of the tv in shown in Figs. 1 or 2. A second web of lilcc character is then wound upon the first, the convolutions of the second \vob crossing: the first so as to ive the column a trussed cll'ccl. After the co unm is completely wound and given the finish coating 10, it. can he snwcxl or cut in the desired length so that its ends shall be smooth and oven, and tho column as a whole, of uniform thickness uml strength at all points. The spiral winding Ill) in opposite directions is indicated I: reference characters 11 and 12 respective F g. 6. After the column has received its finish coating, it can be given a supplemental coat in 12 of water-proof material, this coating being preferably applied while revolving the column in a lathe.

By equipping the coatin with metal reinforcements, as shown in 1g. 2, the transverse reinforcements become lo tudinal reinforcements in the column an the longitudinal reinforcements become horizontal band reinforcements, the column being thus strengthened against bulging under cornpression and against bending and tensile strains.

The diagonal 1, acts as a truss it the banding strengthening it against reinforcement shown in Fig. brace for the column by effect and also bending or break irom the above description it will be appgrent that I have produced a column emdying the features enumerated, and that I have evolved a novel method of makmg such column, and it is to be understood that I reserve the ri ht to make such cha 1n the product an in the method of r ucmg the same as properly fell within t e spirit and scope of the appended claims.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is 2-- 1. The method herein-described of making columns, the same consisting in first coatin a web of flexible material with a materia in a plastic condition, a portion of the web at its forward end being left uncoated by said lastic material, then placing on said plastic material a flexible reinforcing materlal, then winding said flexible web upon a rotating core until the desired diameter is obtained, said uncoated portion of the webbing enveloping said core, then applying a finishing coating or layer to the column thus formed and then withdrawing the core and allowing the plastic mass to harden.

2. A column consisting of a spirally wound web provided with a plastic coating,

a second web provided with a plastic coating and wound upon and in a plane intersecting the winding of the first-named web, and a reinforcement of flexible wire netting em bedded in each layer of lastic material.

In testimony whereof I in the presence of two witnesses.
